Answer:
x=4
Step-by-step explanation:
The question shows an isoceles triangle, which means both sides should equal:
28=9x-8
36=9x
x=4
If x = 3 is a solution, (x - 3) is a factor of f(x).
2x³ + x² - 25x + 12 ÷ (x - 3) [by long division] = 2x² + 7x - 4
so f(x) = (x - 3)(2x² + 7x - 4)
f(x) = (x - 3)(2x - 1)(x + 4)
so 'zeros', or more correctly solutions, are: x = 3, x = 1/2 and x = -4.
[by setting each of the factors equal to 0 and solving for x].
Answer:
He will spend 282,000$ for rent of the apartment in 20 years.
He will spend 288,000$ on mortgage for the house in 20 years.
Step-by-step explanation:
Apartment:
1,175$ x 12 months= 14,100$
14,100$ x 20 years= 282,000$
House:
1,200$ x 12 months= 14,400$
14,400$ x 20 years = 288,000$

The function model that represents the amount of battery left after a period of time is y = 1 ₋ 10%x
Given, Miranda bought a new cell phone which is consuming battery at a rate of 5% for every half an hour.
We are required to establish a function model that depicts how much battery is remaining after a certain amount of time.
Let y represent the amount of battery left.
and x represent the number of hours.
Then 5% per half an hour = 5% × 2 = 10%
Now frame the function model:
The amount of battery left = 1 ₋ (rate percent at which battery is being consumed)(The number of hours left)
⇒ y = 1 ₋ 10%(x)
⇒ y = 1 ₋ 10%x
As a result, we obtained the function model for the battery's remaining capacity as y = 1 ₋ 10%x

Answer:
f(1/3) = 9
Step-by-step explanation:
f(x) = 1/x + 2/x
f(1/3) = 1/(1/3) + 2/(1/3)
f(1/3) = 1(3) + 2(3)
f(1/3) = 3 + 6
f(1/3) = 9
